.IMPROVEMENT IN CULTIVATTORS.

Specification forming part of Letters Patent No. 12,609 dated March 27, 1855.

I To all whom it may concern:

Be it known that I, It. 1?. VANHORN, of Jacksontown, Licking county,- Ohio, have invented a new and'useful Improvementin Cultivators; and I do hereby declare that the followingisa full, clearyand ex-act description thereof, reference being had to the accompanying drawin gs and letters and figuresIofreference marked thereon.

The nature of my improvementconsists in the peculiar form of frame and arrangement of teeth, hereinafter described.

A, Figures 1 and 2, is aframe, madeof oneand-one'fourth-inch square bars of Wroughtiron, made in the shape of an elongated rhombus, the longer diagonal being in the direction of the motion. The object of thus lengthening the frame is to make it run more smoothly and steadily than those as made in the usual way. All the teeth are of steel, the shanks of wroughtiron, the holes in the frame square, and the tops of the shanks have screws out on them that they may be secured by nuts.

. O, the fore tooth, has a cutter-edge and very small nosing. It serves to out the sods and roots. D, the rear tooth, which is the largest of all, and when wet is to be feared, or

the last working of corn is to be. done, serves an excellent purpose by throwing the earth toward the corn, and leaving a fine deep furrow for the water to settle in. The length of the removed.

B is a bracesupporting the-"handles, which are of wood, and pass through staples b I) set in its top.

E is a rear brace, supporting the braoeB at its center.

F is a small cross-head, into which the ends of the handles are bolted or keyed in a substantial manner.

H is the draft-head, to which the horse is hitched.

I am aware that a great number of patents have been issued to inventors for improvements in oultivators by men more ingenious than I am; but I know of none having the peculiarities I have described in mine. Encouraged by the high esteem in which they are held above others used in this sectionot' the 'State, I respectfully ask that a patent may be granted me on the following claim, viz:

The peculiar elongated rhombus shaped wrought-iron frame and arrangement of teeth, the front angle bearing a light steel cuttertooth, and the rear angle alarge shovel-tooth, in the manner and for the purposes set forth.

R. P. VANHORN.
